User Agent string: navigator.useragent
The HTTP specification specifies that the browser should send a short user agent string indicating the name and version number of the browser. But in reality it is not so simple.

told me. Use event bubbling to improve efficiency, which is when event agents (PS: Previously done projects have encountered the need to prevent event bubbling, but the use of event bubbling characteristics to improve efficiency is not yet known). After listening to the interviewer to speak of the rise of posture, back to their own online check, and now summed up as a record of their own learning process it:
Event delegation, also called an event delegate. is a common technique for binding eve

Or it can be divided into 3 categories:
· A. All anonymous proxies do not change your request fields, making the server side look like there is a real client browser accessing it. Of course, your real IP is hidden. The server's webmaster does not think you are using a proxy.
B. Ordinary anonymous agents can hide your real IP, but will change your request fields, may be considered to use the
Prerequisites for using SQL Server Agent alerts1. Create the operator, the user who receives the message2. Create an alert, meet a certain condition to trigger an alert, and respond (execute job or/and notify operator)3. Configure Database Mail for sending message notifications4, SQL Server Agent, Properties---Alert system, mail configuration file, select the corresponding mail system and configuration file
This time, username and password all have input checks.However, IP and uagent are not verifiedWhen we use Admin admin login successful, will be an INSERT statementBecause the program trusts the header information of the browser unconditionally, it constructs the injection by modifying the header information of the HTTP packet.Packet interception/modification using BurpsuiteModify the User-agent field, add a single quotation markuser-agent:mozilla/5.0
Zabbix Agent automatic and active registration
Brief description:
Let's take a look at the active registration function of Zabbix today.
When you have ten machines to monitor, you can add them manually. But what do you do when you have 50, hundreds, or more servers to monitor?
Active Agent Auto-Registration is mainly used for Active agents and automatic Registration with the Server. The problem of inconsist
Dynamic Agent technology is a very important part of the entire Java technology system, which is the basis for us to learn more about the Java framework, and is one of the basic knowledge to understand the framework of spring in depth.1, the concept of the agent in JavaDynamic Agent technology is the proxy object used to produce an object. It seems that you are c

Operations Manager "proxy" is a service installed on a computer. The proxy collects data, compares the sample data with the predefined values, creates alarms, and runs responses. The management server receives the configuration and distributes the configuration to the agent on the monitored computer. You can install the operations manager agent
First, the basic concept of the agent1, the Life of the agent: for example, buy a computer we often buy from agents, rather than directly to the headquarters directly to buy, no matter where to buy the computer is the same, from the agent there to buy we can not run to run, save a lot of trouble.2, the agent in the program: to the existence of multiple target cla
Label:SQL Server Agent is the core of all real-time databases. Proxies have a lot of non-obvious uses, so the knowledge of the system is useful for developers or DBAs. This series of articles will be popular to introduce its many uses.
In this series of previous articles, you reviewed the security roles under the msdb library for authorizing access to SQL Server Agent. These roles include SQLAgentUs
1. Agent Concept Acting as the name implies, instead of others. There is a proxy pattern in design mode, which defines: Provides a proxy for other objects to control access to such objects.The proxy class in proxy mode is doing things in lieu of the delegate class. What the proxy class needs to do is preprocess the delegate class, filter the message, forward the message to the delegate class, and process the message afterwards.
When we learn spring, we know that spring has two main ideas, one is the IOC, the other is AOP, and for IOC, dependency injection doesn't have to be said, and for spring's core AOP, we not only need to know how to satisfy our function through AOP, What we need to learn is how the underlying is a principle, and the principle of AOP is the dynamic agent mechanism of Java, so this essay is a review of the dynamic mechanism of java.In the dynamic
The general use of Linux words are used by the global proxy http_proxy and https_proxy These two environment variables to achieve, but the disadvantage is that this is not a real global agent, even if the agent is set, for some applications are not valid, such as w3m, And this approach does not support the SOCKS protocol.I use Shadowsocks as a proxy in the lab environment to access the extranet, not used to
Brief introductionfor Agents, it is the service proxy that modifies the bytecode before the VM starts and executes the method.for Javassist, a specific implementation of the bytecode is modified.What's the use of these two combinations? writing a test framework is not limited to this.for byte codes:BYTE-code processing tool, BCEL,ASM with virtual machine directives. Javassist uses a Java-encoded method to process bytecode, which is relatively low-performance, but convenient.Official: http://www.

We all know that the two main features of spring are IOC and AOP.IOC is responsible for the dynamic injection of the object into the container, so as to achieve a need to inject who who, when the need to inject the effect of the time, can be described as a recruit, the lingering. Think all feel cool, if the real life also has this ability that is cool crooked, as for how cool, you own brain repair it, and AOP, it is to achieve the container is another great advantage, that is, you can let the ob
